“How To Make It in America” star Bryan Greenberg is quickly learning the phrase That’s What Friends Are For isn’t just a classic song — it’s also what has turned his upcoming Olevolos Charity Event into one of the hottest tickets in NYC.

With Emmanuelle Chriqui, Justin Long, Gina Gershon, Hilarie Burton and the rest of his “How To Make It In America” co-stars turning out for the Tanzania benefit, Bryan is poised to surpass his donation goal … as long as you pitch in!

PopWrap: How did you get involved with The Olevolos Project?

Bryan Greenberg: In 2005, my cousin went to teach English in Tanzania and realized how much help these kids needed. Structure, leadership, basic food, water, medicine – normal things we take for granted. Last Christmas I went with there with couple of friends on safari and after 5 days of seeing animals, we wanted to see the culture. We got into the city, where my cousin introduced me to this guy who runs their orphanage. I was so moved at what was going on that I had to help out any way I could. They need a library, so I wanted to throw an event where we could get some money to try and build that as well as get some computers and help these beautiful kids out any way we can.

PW: What can people expect if they buy a ticket to the event?

Bryan: We’ll have drinks, food and music in addition to this amazing silent auction. You can big on a set visit for “How To Make It In America,” a safari for two to Tanzania, tickets to Bonaroo, lots of cool stuff. My cast will be there, a bunch of my friends too — it’s a great auction and so important to me … so buy a ticket [laughs].

PW: Were you surprised that so many of your co-stars and HBO jumped on the bandwagon to help?

Bryan: In general people want to help out. I think every person wants to help but sometimes they don’t know where to focus their attention. I say, you’d spent $150 on a night out anyway, why not just put it to good use with me and we can have the best food, the best booze and the best time building these kids a library.

PW: I know you’re deep into filming on “How To Make It In America” season two — what can you tease?

Bryan: We’re coming back with a vengeance. It’s funnier, it’s edgier, it’s sexier, there’s a lot more going on. We have the potential to make our business a major, major brand, but with that comes a lot of temptations. We have to question what we’re really doing this for. Then we also bring in some new love interests for the guys – I don’t want to give away too much, but the show literally starts off with a bang.

PW: As in gunshot?

Bryan: There could be gunshots, maybe sex – we got a lot of bangs going on [laughs].
